Es ist bereits bekannt, Natriumsalze sulfonierter Melamin-Formaldehydharze anorganischen Baustoffen zuzusetzen, um deren Verarbeitbarkeit und Festigkeitsentwicklung zu verbessern.It is already known to sulfonate sodium salts Adding melamine-formaldehyde resins to inorganic building materials in order to improve their workability and strength development to improve.

Die bis jetzt bekannten Harze können jedoch für die Praxis nicht in der gewünschten hohen Konzentration hergestellt werden. Sie weisen bereits bei einem Feststoffgehalt von über 35 % eine unbrauchbar hohe Viskosität auf, welche beim Lagern noch zunimmt. Als Salze mehrwertiger Kationen sind diese Harze nicht einsetzbar, da sie unlöslich sind. Bedingt durch die hohe Dosierung dieser Harzlösungen von bis 5 %, bezogen auf das Bindemittelgemisch, gelangen hohe Anteile an Alkalien in den Baustoff. Der negative Einfluss von Alkalien auf die Festigkeitsentwicklung, das -Schwinden und vor allem die Reaktionsfähigkeit mit gewissen silikatischen Zuschlagstoffen ist bekannt. Aus diesem Grunde hat der Sachverständigenausschuss "Betonzusatzmittel" in Deutschland den Alkaligehalt für Zusatzmittel bei Gefahr schädlicher Alkalireaktionen im Beton auf max. 0,02 % Na_0, bezogen auf das Bindemittel ,festgelegt.However, the resins known up to now cannot be produced in the high concentration desired for practical use will. They already show a solids content of over 35% has an unusually high viscosity, which increases during storage. As salts of polyvalent cations these resins cannot be used because they are insoluble. Due to the high dosage of these resin solutions of Up to 5%, based on the binder mixture, high proportions of alkalis get into the building material. The negative influence of alkalis on the strength development, the shrinkage and above all the reactivity with certain silicate Aggregates is known. For this reason, the expert committee "concrete admixtures" in Germany the alkali content for admixtures if there is a risk of harmful alkali reactions in the concrete to a maximum of 0.02% Na_0, based on the binder.

Bekannte PrüfvorSchriften sind z.B. in USA die ASTM Normen C 295, C 227 und C 289.Well-known test regulations are e.g. in the USA the ASTM Standards C 295, C 227 and C 289.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, hochkonzentrierte, niederviskose, den Wassergehalt vermindernde, wasserlösliche und lagerfähige Zusatzmittel zur Verfügung zu stellen, die auch in alkalifreier Form eingesetzt werden können. Mit den erfindungsgemässenThe present invention is therefore based on the object of providing a highly concentrated, low-viscosity water content To make reducing, water-soluble and storable additives available, also in alkali-free Form can be used.

Polykondensationsprodukten können die Verarbeitbarkeit und die physikalischen und chemischen Eigenschaften von Baustoffen verbessert werden.Polycondensation products can affect the processability and the physical and chemical properties of building materials be improved.

Die Kondensationsprodukte können erfindungsgemäss auch als Lösungen ihrer Salze mehrwertiger Kationen, z.B. des Calciums eingesetzt werden, wodurch alle negativen Einflüsse der Alkalien eliminiert werden. Die erfindungsgemässen Harze können daher ohne Bedenken als Zusatzmittel zu Baustoffen mit alkalireaktiven Zuschlagstoffen verwendet werden. According to the invention, the condensation products can also be used as solutions of their salts of polyvalent cations, e.g. of calcium, whereby all negative influences the alkalis are eliminated. The resins according to the invention can therefore be used without hesitation as additives to building materials with alkali-reactive aggregates.
